Mrs. Billett's White Cake (layers only)

Parchment paper
1 cup milk
1and1/2 tsp. vanilla extract
1 cup butter, softened
2 cups sugar
3 cups cake flour
1tbsp baking powder
5 egg whites

1. Preheat oven to 350 degrees. Grease 3 (8-inch) round or square cake pans; line bottom with parchment paper, and grease and flour it (the paper).
*While the butter is thawing in a separate container complete steps 2 and 3. You can also heat butter in the microwave for 30 seconds at full heat to speed the process.
2. Stir together milk and vanilla.
3. Stir together flour and baking powder.
4. Beat butter at medium speed with a mixer until creamy; gradually add sugar, beating until light and fluffy.
5. Alternately, starting and ending with flour mixture and milk mixture add to butter mixture. Beat until blended after each addition.
6. Beat egg whites at a medium speed until stiff peaks form; gently fold into batter. Pour batter into prepared pans.
7. Bake at 350 degrees for 20 to 23 minutes or until wooden stick comes out clean. Let cool.
*It is good to have 2 or 3 baking pans because you can bake all the layers at the same time. I used only one and when i was putting in the parchment paper the second and third time it did not come out very straight so my layers were a bit crooked. Also, having 3 baking pans helps have even amount of dough in each.
